膜世界模型的太阳系试验

Solar system tests of brane world models

Christian G. Boehmer, Tiberiu Harko, Francisco S. N. Lobo

摘要:

考虑了膜世界模型中球对称静态真空场方程的Dadhich、Maartens、Papadopoulos和Rezania(DMPR)解的广义相对论经典检验(近日点进动、光偏转和雷达回波延迟)。对于这个解,膜世界恒星外部真空中的度规类似于经典广义相对论的赖斯纳-诺德斯特龙形式,电荷的作用是由第五维投影产生的潮汐效应所起的作用。关于水星近日点移动、围绕太阳的光弯曲(使用长基线无线电干涉测量法获得)以及使用海盗号着陆器到火星的测距的现有太阳系观测数据,限制了整体潮汐参数和膜张力的数值。

英文摘要:

The classical tests of general relativity (perihelion precession, deflection of light, and the radar echo delay) are considered for the Dadhich, Maartens, Papadopoulos and Rezania (DMPR) solution of the spherically symmetric static vacuum field equations in brane world models. For this solution the metric in the vacuum exterior to a brane world star is similar to the Reissner-Nordstrom form of classical general relativity, with the role of the charge played by the tidal effects arising from projections of the fifth dimension. The existing observational solar system data on the perihelion shift of Mercury, on the light bending around the Sun (obtained using long-baseline radio interferometry), and ranging to Mars using the Viking lander, constrain the numerical values of the bulk tidal parameter and of the brane tension.
